CMM- Coordinate Measuring Machine, for the uninitiated. That was cool work Mitch. I did a little bit as a tool maker apprentice.
I was a tool maker at a company that did contract work for the big three. We did individual stampings (fenders, roofs, floor pans, wheel wheels, whatever) and sub assemblies (inner and outer hoods, doors, trunk lids, hatch lids, etc)
Individual panels were pit in an inspection fixture and measured with go-no go gauges, as I remember. It's been a while and I didn't work QC. We didn't assemble bodies in our plant.
Near the beginning of the video, you can see dies stamping roofs. The gray part is the die itself. (you can only see the upper, there is a matching, opposite lower below the stamping) That's what I built.
I only worked there 10 years. They were in business for 85 years and folded up basically because of the old technology they used, and resulting inefficiency. Those robots put a lot of assembly workers on the street. They did add to the skilled trades, though.
